when I first flew to Bangkok in the 1990s there was an airport, later this modern one was added and airport 1 became the airport for local flights in Thailand. THERE was no Skytrain subway and the traffic was hopeless. Also many domestic flights did not exist yet, very old taxis were driving around and old buses and many Tuk-tuks. Bangkok and Thailand have changed a lot for the better in 30 years. The medical facilities are of a very high standard and can compete with the best hospitals in the USA and the EU.
